The party was unfortunately prevented from reaching the top of Mount St. Elias by severe storms, but the ascent was so nearly accomplished that Mr. Russell is confident he found a practicable route; and it seems probable that had he been started ten days or two weeks earlier the first ascent of Mount St. Elias would have been recorded as a part of the work of the expedition. The full report of this expedition is now nearing completion, and will be published by the Society at an early date. To this I must refer you for the interesting details, and experiences encountered by the explorers. The expedition was organized by the Society, but in congratulating ourselves we should not forget that our thanks are due to the United States Geological Survey for the assignment of officers to conduct the work in the field and for assistance rendered in the organization; and we may hope the substantial results that have been secured will prove as pleasing to that great national work as they are to your board of managers. _Washington, January 23, 1891_.
